I've cut it down to as basic as i can for now and made sure nothing is interfering with the collision groups as you mentioned, but the same issue is still occuring.

I've attatched the sourcefile and the test map(you need to rename the testmap to .bsp) that i'm testing the code on, feel free to compile it and test the barrel collisions, as i may not have described the issue correctly.

I may just try use solid bounding boxes and manual set the collision range of each barrel model, but its not the most elegant collision model.

I changed

SetEntPropVector(eBarrel, Prop_Send, "m_vecOrigin", sPos);

to

TeleportEntity(eBarrel, sPos, NULL_VECTOR, NULL_VECTOR);

And the barrels are now solid, guess there's your solution

weird, that worked! cheers, all is good now

You should probably use Stripper:Source, it's faster, safer and more powerful.
